• Check the measuring instrument and test leads for signs of damage before each measurement. Never
take measurements if the protective insulation is damaged (torn, missing, etc.). The test leads come with
a wear indicator. A second layer of insulation will become visible if the lead is damaged (the second layer
of insulation is a different colour). If this occurs, discontinue use and replace the measurement accessory.
• Do not use the multimeter just before, during or just after an electrical storm (electric shock /high-power
surges!). Ensure that your hands, shoes, clothes, the floor, circuit and circuit components are dry.
• Avoid using the device in the immediate vicinity of:
- Strong magnetic or electromagnetic fields
- Transmitting antennas or HF generators.
• These may distort the measurements.
• If you suspect that safe operation is no longer possible, discontinue use immediately and prevent unau-
thorised use. Safe operation can no longer be assumed if:
- There are signs of damage
- The device does not function properly
- The device was stored under unfavourable conditions for a long period of time
- The device was subjected to rough handling during transport.
• Do not switch the device on immediately after it has been brought from a cold room into a warm one. The
condensation generated may destroy the product. Leave the device switched off and allow it to reach
room temperature.
• Do not leave packaging material lying around carelessly, as it may become a dangerous toy for children.
Lithium battery, lithium-ion battery and charger
• Only recharge the lithium-ion battery with the enclosed charger. The use of a different charger can lead
to explosion of the battery. There is a risk of fire and explosion!
• Store the battery dry and at room temperature. If possible, use a special storage container (e.g. LiPo
bags as in model construction).
• The battery must not be exposed to temperatures >60 °C (e.g. vehicle interior in summer, etc.).
• The battery must not get damp or wet.
• Charge the battery only under supervision. Stop the charging process immediately if you identify any
irregularities on the battery pack (e.g. battery has expanded, etc.).
• Do not dismantle batteries, do not short-circuit them or throw them into a fire. Never attempt to recharge
disposable batteries. There is a risk of explosion.
• To prevent battery leakage, remove the battery when you do not plan to use the product for an extended
period of time. Leaking or damaged batteries may cause acid burns when they come into contact with
skin. Therefore, use suitable protective gloves to handle damaged batteries.
